Answer:
m<b= 88º
m<C=44º
m<A=48º (given)
Step-by-step explanation:
180=48+x+x-44
180=4+2x
176=2x
x=88
x-44=44
Answer:
∠A = 48°
∠B = 88°
∠C = 44°
Step-by-step explanation:
We know that the angles in a triangle, added together, equal 180°. Because of this information, we can know that angle A, plus angle B, plus angle C should come out to a total of 180°.
So, how can we represent this using algebra? It should look like this:
[tex]48+x+(x-44)=180[/tex]
Now, it shouldn't be that hard to solve for x. My steps are shown below:
[tex]48+x+(x-44)=180\\48+x+x-44=180\\x+x+48-44=180\\2x+4=180\\2x=176\\x=88[/tex]
Now we know what x is equal to, and we can find the measure of each angle. Angle A we already know the measure of, it's 48°. Angle B has a measure of x, and we know x is equal to 88°. Angle C is equal to x - 44, which is equal to 88 - 44, or 44°.
Hopefully that makes sense! If you have questions, let me know. :)

How do I do this and what is the working out to this problem9x - 27y³
substitute y=-3x+4, y=3x-2
Answer:
No solution
Step-by-step explanation:
Here you're given a system of two linear equations. It seems as though your goal is to solve this system for x and y, using the substitution method.
Start by setting y = -3x + 4 equal to y = 3x - 2. This eliminates y. But it leaves you with 4 = -2, which is always false. Thus, the given system has no solution. If you were to graph the two lines, you'd see that they are parallel and never intersect.

Triangle PQR is scaled up by a factor of 2 and then reflected about the y axis and is named as triangle XYZ. Which statement is true?
[tex]\triangle PQR[/tex] is not congruent to [tex]\Delta XYZ[/tex] because a non-rigid motion was performed. (Correct choice: B)
A motion is rigid if and only if the Euclidean distance between any two points of an affected geometrical figure is conserved, there are four operations considered for rigid motion:

2. Triangle ABC is equilateral and AB = 6x + 3, BC = 8x - 1,2. AB =
and AC = 11x - 7. Find x and the measures of
each side of the triangle.
Answer:
AB = BC = AC = 15
Step-by-step explanation:
Since the triangle is equilateral then the 3 sides are congruent.
Equate any 2 sides and solve for x , that is
AC = AB , so
11x - 7 = 6x + 3 ( subtract 6x from both sides )
5x - 7 = 3 ( add 7 to both sides )
5x = 10 ( divide both sides by 5 )
x = 2
Then
AC = 11x - 7 = 11(2) - 7 = 22 - 7 = 15 , thus
AB = BC = AC = 15

The figure below shows a quadrilateral ABCD. Sides AB and DC are congruent and parallel:
A quadrilateral ABCD is shown with the opposite sides AB and DC shown parallel and equal.
A student wrote the following sentences to prove that quadrilateral ABCD is a parallelogram:
Side AB is parallel to side DC, so the alternate interior angles, angle ABD and angle CDB, are congruent. Side AB is equal to side DC, and DB is the side common to triangles ABD and BCD. Therefore, the triangles ABD and CDB are congruent by SSS postulate. By CPCTC, angles DBC and BDA are congruent and sides AD and BC are congruent. Angle DBC and angle BDA form a pair of alternate interior angles. Therefore, AD is congruent and parallel to BC. Quadrilateral ABCD is a parallelogram because its opposite sides are equal and parallel.
Which statement best describes a flaw in the student's proof?
Question 11 options:
Angle DBC and angle BDA form a pair of vertical angles, not a pair of alternate interior angles, which are congruent.
Triangles ABD and CDB are congruent by the SAS postulate instead of the SSS postulate.
Triangles ABD and BCD are congruent by the AAS postulate instead of the SSS postulate.
Angle DBC and angle BDA form a pair of corresponding angles, not a pair of alternate interior angles, which are congruent.
Answer/Step-by-step explanation:
"Side AB is parallel to side DC so the alternate interior angles, angle ABD and angle CDB, are congruent." True
"Side AB is equal to side DC and DB is the side common to triangles ABD and BCD." True
Now we have 2 triangles, with 2 congruent sides, and the angles between these pairs of congruent sides, are also congruent..
This means that:
Therefore, the triangles ABD and CDB are congruent by SAS postulate, NOT SSS postulate, which would require 3 pairs of congruent sides.
Answer: Triangles ABD and CDB are congruent by the SAS postulate.
Three families live in the same apartment building. They decided to share a giant 220-ounce container of laundry detergent. If the families split the detergent equally, how many ounces of laundry detergent will each family get?
Answer:
73.333 OuncesStep-by-step explanation:
Lets name the 3 families Family A, Family B, and Family C. Now, they decided to divide the giant 220-ounce container into 3 different families. We need to divide 220 by 3 to find out how many ounces will one family get.
Step 1: Divide
=> 220 ÷ 3
=> 73.333
So, each family will receive 73.333 ounces. I hoped this helped.

Part III: Do the points in the following set lie on the same line? Explain your answer. Show all work. (4 points) A (1, 3) B (4, 2) C (–2, 4)
Answer: Yes they are all on the same line.
Step-by-step explanation:
We can find an equation between two of the points and check to see if the third point is also a solution. I'll pick (1,3) and (-2,4) and calculate a slope:
y = (4-3) = 1
x = -2 - 1 = -3
slope = y/x
slope = -1/3 or -0.3333
The equation, so far, is:
y = -(1/3)x + b
We can find b by entering one of these points into the equation and solving for b. I'll pick (-2,4):
y = -(1/3)x + b
4 = -(1/3)(-2) + b
4 = (2/3) + b
b = 3 1/3 or 10/3
The equation is
y = -(1/3)x + 10/3
This equation goes through the two points we used to cacluate the slope. The third point, (4,2) can be checked to see if the equation gives us a y value of 2 if we set x=4:
y = -(1/3)x + 10/3
y = -(1/3)*(4) + 10/3
y = -(4/3) + 10/3
y = 6/3 or 2
It correctly returns a value of 2, so (4,2) is also on this line.
Kaite went out for dinner with her friends and left 17% tip. If b represents the bill, an expression that represents the total bill she will pay.
Answer:
1.17B
Step-by-step explanation:
Katie and her friends will pay 17% of the bill, B.
Therefore, we have to add 17% of B to B to find how much they will pay:
17/100 * B = 0.17B
Therefore, the total bill will be:
Bill + tip
= B + 0.17B = 1.17B
The expression that represents the total bill they will pay is 1.17B

Yesterday, the movie theater brought in $1,440 in ticket sales and $295.25 in food sales. Today, ticket sales were three-fourths as much as yesterday, and food sales were down by $33.50. Nina wrote the expression.
3/4 (1440) + 295.25 + (-33.50)
to find today's total sales. Is she correct? Explain.
Answer/Step-by-Step-Explanation:
Yes, She is Correct Because It say " Yesterday, the movie theater brought in $1,440 in ticket sales and $295.25 in food sales" and then it say Today ticket sales were 3/4 as much as yesterday..
So the key Numbers are:
$1,440 and 295.25 and 3/4
Then it say food say went down by $33.50
the Key Words are "Went Down" Meaning -$33.50
Therefore 3/4 · (1440)+295.25+(-33.50)
Hence, Nina is Correct.
(Ask If Answer to 3/4 · (1440)+295.25+(-33.50) Needed)
Answer:
Step-by-step explanation:
Nina is correct. Her expression represents the scenario because it takes ¾ of the ticket sales and subtracts $33.50 from the food sales.
